In the term shown in the dij'awii the lltlt dl'fpOSli l is journaledwithin a tubular housing or rudder-pipe 2 and carries its upper end a*worm-geacsector 3 which meshes with a horizontally disposed wormjournaled at one side of the rudder-post. A Dllll of universal joints 5and an inclined shaft 6 connect the worm with a line-shaft 1 locatedbelow the door or deck 8 oil the vessel.

l'lxtending longitudinally tin-nigh the tubular steering post 10 is apair ol shafts l5 and 16 preferably located one concentrically witiiinthe other. These are journaled in a stationary tube 17 supported by abracket 18 below the pedestal and are separately rotatable. each beingentirely independent of the steering-post l0. the upper ends oi theshafts and 16 are smallv hand-levers ll), which may have the usualdetent pawls coacting with suitable racks above the steering-wheel as inan automobile. The lower ends of the shafts l5 and 16 extend below thesupporting bracket 18 and are provided with arms or fittings 20 and 21,which in turn are provided with links for connecting the arms 20 and illwith the cables or rods which respectively control the spark timer andthe admission oi fuel to the motor. The arms 20 and 21 extend upwardlyaroiuid the gear 14L into a pocket Ql in the base of the podestal 11 inorder to enable the connection to the engine to be made above the levelof the deck 8.

When the steering-wheel 5) is rotated the movement is transmitted by thesteeringpost 10 and bevel gears to the shaft 7, thence to the universaljoints and inclined shaft 6 to the worm 4t which in turn rotates thegearsector 3 and. the rudder post 1. his the worm-gearing is selflocking the riulder will remain in any position in which it is set andno strain upon the rudder will be transmitted to the steering-wheel.Thehandlevers 19, being within convenient reach of the operators handswhile he grasps the wheel 9 enable him to advance or retard the sparkand regulate the fuel food without releasing his hands from thehand-wheel 9, this mechanism being siniili in function to thecorresponding mechanism in an automd bile steering-gear.

Although but one specific embodiment of this invention has been heroinshown and described, it will be UDClGStOOCl that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as detined by the following claims.

I claim:

1. In a device of the class described, the combination of a rudder, avertically disposed steering-posh a. pedestal in which saidsteering-post is journaled, mechanism connecting the lower end of saidsteering-post with said rudder for opera the latter l idly in fixedposition, and a longitudinally through the rotation of saidsteering-post, a bracket below said steering-post, a tubular shaft'rotatably supported by said bracket and extending longitudinallytirough said steering-post, a second shaft extending through saidtubular shaft, means at the upper end of said tubular and second shai'tsfor separately rotating them, and arms at the lower ends of said tubularand second shafts adapted for operating controlling devices of anengine, said arms being bent upwardly and extending upward outside ofsaid steering-post.

2. In a boat having a floor with an opening thereunder, an uprightrudder post at the rear end, in combination with steering meanspositioned forward of said rudder post and projecting downwardly belowsaid floor, a concealed and longitudinally disposed shai t rotatablyjournaled in a substantially horizontal position in said opening beneaththe floor and operatively geared at its forward end to the lower end ofsaid steering means, a horizontally disposed and laterally projectinggear sector rigidly attached to the upper end of said rudder post, alongitudinally disposed worin journaled beside and arranged to meshoperatively with said gear sector for oscillating the same and adaptednormally to hold the same rigdisposed and downwardly inclined shat'thaving universal joint connection at its upper and rear end with theforward end of said worm, the forward end of said inclined shaft beingarranges to project beneath the saidfioor and having universal jointconnection with the rear end of said concealed shaft.

3. In a boat of the class described, a rud der post journaled insubstantially vertical position, in combination with a substantiallyhorizontally disposed and laterally projecting gear sector fixed to theupper end of said rudder post, a worm disposed substantiallylongitudinally and journaled to mesh operatively with said gear sector,an inclined shaft having universal joint connection at its upper rearend with the forward end of said worm, and at its forward and lower endprojecting downwardly beneath the floor of the boat, and steering ineansoperatively connected beneath the floor with the said forward and lowerend of the inclined shaft.
